Missed opportunity to buy merch

I proposed to my girlfriend a few hours before the Fenway show last night and the concert was our celebration. I intended to buy merch using the QR code but had no idea I had to be within a 50 mile radius. We got home to Connecticut (we appreciated the shout out lol) last night and I realized I can’t buy anything. I’m really disappointed because we wanted some shirts to remember the night.

Will they sell Fenway specific merch at all on the website? Any other ideas for how we can buy a few things?
